Allocating the QMF trace data output

You must allocate the QMF trace data output before you start QMF if tracing is to be used.

You might want to reallocate the data set or data queue if the original allocation does not meet your needs.

For examples of how to allocate QMF trace data output for TSO, see the programming language specification for the language you are using.

The commands in the examples allocate a sequential trace data set or data queue that you can examine after your QMF session is over. The output consists of fixed-length, 80-character records.

For CICS®, you can use program parameters DSQSDBQT and DSQSDBQN to specify where QMF puts your trace data. Use caution when using CICS temporary storage, because QMF can produce a large amount of trace data. Because trace data that exceeds the size of the queue is discarded, use CICS temporary storage only for trace data from messages or small applications.
